Method for providing positioning service, base station and terminal

A method for providing a positioning service, applied to a terminal, the method comprising:

• receiving positioning service provision capability indication information issued by a base station, of which a serving cell is under coverage, wherein the positioning service provision capability indication information comprises at least one of indication information about whether the base station supports the positioning service, information about one or more positioning service types supported by the base station, information about one or more positioning function types supported by the base station, accuracy information of the positioning service supported by the base station, or delay guarantee information;
• reporting a positioning service request to the base station according to the positioning service provision capability indication information;
• and
• receiving corresponding positioning service information provided by the base station according to the positioning service request,
• wherein a manner for bearing the corresponding positioning service information is determined by the base station according to a number of terminals initiating positioning service requests within a predetermined time or a predetermined service period;
• or,
• a manner for bearing the corresponding positioning service information is determined by the base station according to a number of terminals for which the positioning service is required to be provided within a predetermined time or a predetermined service period;
• or,
• a manner for bearing the corresponding positioning service information is determined by the base station according to an information amount of the positioning service expected to be sent within a predetermined time or a predetermined service period;
• or,
• total data amounts corresponding to different sending manners are determined by the base station according to a number of the terminals for which the positioning service is required to be provided and a positioning information amount within a predetermined time or a predetermined service period, and a bearing manner with a smallest total data amount is selected as a manner for bearing the corresponding positioning service information provided for the terminal;
• or,
• a manner for bearing the corresponding positioning service information is determined by the base station according to a delay parameter contained in the positioning service request.

A base station, comprising a processor and a memory storing computer-readable operation instructions, wherein when the computer-readable operation instructions in the memory are run, the processor is configured to:

• send positioning service provision capability indication information to a terminal, wherein the positioning service provision capability indication information comprises at least one of indication information about whether the base station supports positioning service, information about one or more positioning service types supported by the base station, information about one or more positioning function types supported by the base station, accuracy information of the positioning service supported by the base station, or delay guarantee information;
• receive a positioning service request reported by the terminal according to the positioning service provision capability indication information;
• and
• provide, according to the positioning service request, corresponding positioning service information for the terminal,
• wherein the processor is specifically configured to:
• determine a manner for bearing the corresponding positioning service information provided for the terminal according to a number of terminals initiating positioning service requests within a predetermined time or a predetermined service period;
• or,
• determine a manner for bearing the corresponding positioning service information provided for the terminal according to a number of terminals for which the positioning service is required to be provided within a predetermined time or a predetermined service period;
• or,
• determine a manner for bearing the corresponding positioning service information provided for the terminal according to an information amount of the positioning service expected to be sent within a predetermined time or a predetermined service period;
• or,
• determine total data amounts corresponding to different sending manners according to a number of the terminals for which the positioning service is required to be provided and a positioning information amount within a predetermined time or a predetermined service period and select a bearing manner with a smallest total data amount as a manner for bearing the corresponding positioning service information provided for the terminal;
• or,
• determine a manner for bearing the corresponding positioning service information provided for the terminal according to a delay parameter contained in the positioning service request.
